3GPP Architecture for 5G NR
September 21, 2022

As per 3GPP, The gNB is divided into two logical functions: the CU and DU. The DU is the baseband unit in a 5G RAN. It handles layer 1 and […]

The Difference between SIBs in 4G and 5G
October 8, 2021

As you may know that UE can access the network if it can receive some of the System Information (SI) from the Cell (Mandatory). So Let’s understand the main difference […]

What is the Importance of massive MIMO in 5G NR?
December 29, 2020

5G new radio (NR) is conceived to provide new service types, namely, enhanced mobile broadband (eMBB), ultra-reliable and low latency communications (URLLC), and massive machine-type communications (mMTC). Among these, eMBB […]

What is the difference between RRC_IDLE and RRC_Inactive?
December 8, 2020

RRC_IDLE The UE is in the idle state when there is no RRC connection established. In RRC_IDLE: A UE specific DRX cycle may be configured by upper layers. UE monitors […]

5G NR Synchronization Signal Block (SSB)
November 22, 2020

In previous cellular technologies (LTE, LTE-M, NB-IoT), cell-specific synchronization and reference signals were used. Always-on reference signals were spread over the entire spectrum for precise channel estimation. 5G NR is […]

RAN Virtualization in 5G Network
